What is fast-jwt?

The fast-jwt package is a high-performance JSON Web Token (JWT) library for Node.js. It is designed to be fast and efficient, providing a simple API for creating, verifying, and decoding JWTs.

What are fast-jwt's main functionalities?

Creating a JWT

This feature allows you to create a JWT using a secret key. The `createSigner` function generates a signer function that can be used to sign payloads and create tokens.

const { createSigner } = require('fast-jwt');
const signer = createSigner({ key: 'your-secret-key' });
const token = signer({ userId: 123 });
console.log(token);

Verifying a JWT

This feature allows you to verify a JWT using a secret key. The `createVerifier` function generates a verifier function that can be used to verify tokens and extract the payload.

const { createVerifier } = require('fast-jwt');
const verifier = createVerifier({ key: 'your-secret-key' });
try {
  const payload = verifier(token);
  console.log(payload);
} catch (err) {
  console.error('Invalid token', err);
}

Decoding a JWT

This feature allows you to decode a JWT without verifying its signature. The `decode` function extracts the payload from the token.

const { decode } = require('fast-jwt');
const payload = decode(token);
console.log(payload);
